具体实施方式 detailed description
下面结合具体实施例对本实用新型作进一步说明。 Below in conjunction with specific embodiment the utility model is further described.
如图1至图3所示，本实施例所述的高温型风力发电机组轮毂系统用的散热结构，是以风力发电机机组传统轮毂为基础，考虑由于外界环境高温和轮毂自身设计对轮毂系统散热的影响，在保证轮毂满足各极端风况的前提下，在风力发电机组的整流罩4顶盖前端开有一个进风口1，并内增有一段连通该进风口1和风力发电机组轮毂5内部的通风管2，同时，在所述轮毂5的后端开有三个均布在轮毂5的变桨驱动法兰周围的通风孔3，以增加轮毂系统的散热空间，将轮毂系统的散热空间有效扩展到整流罩4，进而通过引入自然风来增强轮毂内外空气的对流，在一定程度上降低了轮毂系统产生的的热量对机组运行的影响。 As shown in Figures 1 to 3, the heat dissipation structure for the high-temperature wind turbine hub system described in this embodiment is based on the traditional hub of the wind turbine generator set, considering the impact on the hub system due to the high temperature of the external environment and the design of the hub itself. For the effect of heat dissipation, under the premise of ensuring that the hub meets the extreme wind conditions, an air inlet 1 is opened at the front end of the top cover of the fairing 4 of the wind turbine, and a section is added to connect the inlet 1 and the hub 5 of the wind turbine. Inside the ventilation pipe 2, at the same time, there are three ventilation holes 3 evenly distributed around the pitch drive flange of the hub 5 at the rear end of the hub 5, so as to increase the heat dissipation space of the hub system and reduce the heat dissipation space of the hub system. It is effectively extended to the fairing 4, and then the convection of the air inside and outside the hub is enhanced by introducing natural wind, which reduces the influence of the heat generated by the hub system on the operation of the unit to a certain extent.
此外，考虑到风场存在沙尘的情况，在进风口1处使用过滤网6，并用螺栓将过滤网6固定，这样如果遇到沙尘天气，空气将会通过整流罩前端的过滤网6进行过滤，避免沙尘进入轮毂内部。再者，考虑到风场存在降水的情况，在所述通风管2的前端使用吸水布包覆起来，然后使用喉箍固定起来，这样即使遇到降雨天气，雨水会被通风管前端的吸水布吸附，避免降水进入轮毂内部。到了冬季天气寒冷，为了避免寒冷空气过量进入轮毂对变桨系统带来异常后果，冬季可以通过增加挡风板将通风管2封闭。 In addition, considering the presence of sand and dust in the wind field, a filter 6 is used at the air inlet 1, and the filter 6 is fixed with bolts, so that in case of sand and dust, the air will pass through the filter 6 at the front end of the fairing. Filter to prevent sand and dust from entering the interior of the hub. Furthermore, considering that there is precipitation in the wind field, the front end of the ventilation pipe 2 is wrapped with an absorbent cloth, and then fixed with a throat hoop, so that even in rainy weather, the rainwater will be absorbed by the absorbent cloth at the front end of the ventilation pipe. Adsorption prevents precipitation from entering the interior of the hub. When the weather is cold in winter, in order to avoid excessive cold air entering the wheel hub and causing abnormal consequences to the pitch system, the ventilation duct 2 can be closed by adding a windshield in winter.
以上所述之实施例子只为本实用新型之较佳实施例，并非以此限制本实用新型的实施范围，故凡依本实用新型之形状、原理所作的变化，均应涵盖在本实用新型的保护范围内。 The implementation examples described above are only preferred embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model, so all changes made according to the shape and principle of the present utility model should be covered by the scope of the present utility model. within the scope of protection.
